9. CONNECTION TO FANUC I/O Link
375
NOTE
1 Xm+3.0 to 3.7 have a common line that is possible to select the source/sink type. If DICOM
(CM69–B06pin) is connected to +24V, the DI signal logic is negative. But in this connection,
if the DI signal wires happen to drop the ground level, the status of the DI signal is same as the
DI signal is ”ON”. From the safety viewpoint, DICOM should be connected 0V.
2 From the safety viewpoint, Emergency Stop signal must be assigned on the address Xm+0.0
to 0.7 or Xm+1.0 to 1.7 or Xm+2.0 to 2.7. As refer to the 5. DI/DO mapping, assign the
Emergency stop DI.
3 Xm+0.0 to 0.7, Xm+1.0 to 1.7 and Xm+2.0 to 0.7 common lines are fixed. So, if these DI pins
in this address open, the status of these one stay ”0”. And in case of Xm+3.0 to 3.7 which have
a selectable common line, if the DICOM (CM69–B06pin) is connected to 0V and these DI pins
open, the status of these one stay ”0”. And if the DICOM are connected to +24V and these DI
pins open, the status of these one stay ”1”. And if the DICOM is not connected to 0V or +24V
and these DI pins open, the status of these one don’t care.
